• Founded in the spirit of IAP in May 2004,
IANAS is a regional network of Academies of Sciences created to support cooperation towards the strengthening of science and technology as a tool for advancing research and development, prosperity and equity in the Americas.
CREACION DE IANAS Santiago, Mayo, 2004
• The original proposal for the Science
Education Program was generated by
Jorge Allende, of the Chilean Academy of
Sciences and the final version was approved in the IANAS General Assembly meeting held in Santiago May 5-7, 2004 as follows:
The general objective of this programme is to improve the level and the relevance of science education in the hemisphere through the active participation of Science
Academies and the most prominent scientists in the nations of the Americas working together with teachers and educational authorities.
•Focus
• Why Science Education ?
• Science education is the most important way through which national societies of all countries learn about science, its values, concepts and objectives, and through which they can understand the importance of scientific endeavour for their cultural and socioeconomic development.
Why IBSE
T he Academies of the world have recommended to use IBSE because:
• Inquiry leads to understanding through learners’ own activity and construction of knowledge
• IBSE develops scientific literacy: i.e. appreciation of what science is and does
• IBSE develops cognitive skills (including metacognition) needed for life-long learning
• All these are outcomes needed for citizens of a world permeated by science and technology.
Wynne Harlen, PhD
Visiting Professor, University of Bristol
Meaning of IBSE
• Students raising questions and gathering and using evidence from investigations of the world around to answer them, sharing ideas, advancing ideas through dialogue
• Teachers leading students to develop the skills of inquiry and the understanding of science concepts through the students’ own activity and reasoning, organising group work, debate and access to materials and information sources.

Structure of the IANAS Programme on Science Education
• IANAS Academies decide freely to participate in this Programme.
• One Representative or Focal Point from each participating Academy will conform the Hemispheric Council for the IANAS
Science Education Programme. This
Council will meet annually and will decide on the major policies and activities of the
Programme.
• The council elects a coordinator and a vicecoordinator.
• The coordinator will act as executive secretary of the program for a two years period.
• The vice-coordinator will replace the coordinator for the following period. The council most confirm the replacement by election.
• At the end of his period, the coordinator becomes past-coordinator.
• The three of them work together as an executive committee.
• Policy
• All the activities sponsored by the IANAS
Programme for Science Education (IANAS-PSE) should receive significant funding from the host
Academy or other national institutions in the host country.
• The IANAS-PSE will provide funds that will primarily cover costs for international participation. The funds for the support of these activities will be obtained from grants and direct contributions given to IANAS by national or international public or private institutions.
• The budget of the Programme will depend on the financing obtained.
• U p to 2006 financing came from IAP only.
• On March 2005 the Coordinator and the Chilean
Academy of Sciences presented a pre-proposal on the
Science Education Program to OAS.
• After several visits and letters and other presentation by the Colombian Academy , OAS-FEMCIDI said a final version of the project had to be presented and it had to be coordinated by the Chilean Academy which originally presented it.
• A final proposal was presented by Jorge Allende and the
Chilean Academy in January 2007 requesting USD
$330,000 for 3 years project. The proposal was approved by OAS-FEMCIDI and USD $63,000 were allotted for the year 2007. The activities for 2007 and a tentative budget for 2008 were approved during the Focal Points meeting in July 2 and 3 USD144,000 were granted for year 2008-
2009.
• In November 21/2007, the Academia
Mexicana de Ciencias signed agreements with the Science Academies of seven countries to implement the program “La
Ciencia en tu Escuela”. The Academia
Mexicana is contributing with 400,000
Mexican Pesos (Approximately
USD35,000) for each country. The seven countries are. Guatemala, Costa Rica,
Panamá, República Dominicana,
Colombia, Perú y Bolivia.
ACTIVITIES 2004 - 2006
• Activities started in October 2004 when the first meeting of the Council took place in Santiago.
Jorge Allende from the Chilean Academy of
Sciences, who presented the original proposal of the Program to IANAS, was elected as coordinator for the period 2004 2006. José A.
Lozano from the Colombian Academy, was elected as vice-coordinator.
• The activities for 2005 were approved.

• Through the efforts of the IANAS Co-
Chairs and also in response to the specific requests of several Academies to their respective national representatives, the
IANAS Science Education Program was approved as a Hemispheric Initiative by the Science Ministers of the Americas who met in Lima on November 11, 2004.

• The Academia Mexicana de Ciencias has established the program “La Ciencia en tu
Escuela”
• (http://www.amc.unam.mx/lacienciaentuescuela.ht
m) which was conceived, structured and coordinated by scientists from the Academy.
• The program has been supported by the
Secretaria de Educación Pública in the Federal
District and the Consejo Nacional de Fomento
Educativo in 5 states. The program seeks for methods that will awake the interest in science of children and youngsters through a better
• interaction with teachers and the active participation in simple experiments.
• The program is directed to teachers and students of primary
• and secondary level. Both the scientists and the teachers participate on a voluntary basis. The program initiated in year 2002 is currently
• present in 14 states and has instructed 2666 teachers of 983 schools. It has been evaluated comparing the attitudes and the performance of
• teachers and children from 5th and 7th grades non-participants teachers and students

• January,2006. Workshop on Experimental Chemistry for teachers of Natural Sciences.
• February, 2006. Mathematics for Secondary School Teachers.
• March 2007. Workshop on IBSE Methodologie for Science
Teachers of elementary and and secondary level from Miguel
Grau School.
• Implementation of the first pilot IBSE project in elementary school at Miguel Grau school in second and fourth grades.
• IBSE methodology is applied in courses of mathematics in four different grades at Miguel Grau secondary school.
• International Workshop for IBSE trainers
CHALLENGES
• The biggest challenge is to bring IBSE methodology for the teaching of science to every teacher and every child in
America. This is a tremendous work that will take many years of continuous and dedicated effort. As it is said in the
STATEMENT ISSUED AFTER THE WORKSHOP HELD AT
THE PONTIFICAL ACADEMY OF SCIENCES ON19-20-21
NOVEMBER 2001
“4. Such a challenge cannot be met without the deepest commitment on the part of the various members of the world’s scientific and technological community. Meeting this challenge must be viewed as a new moral obligation.
5. Every means should be used to convey the urgency of the situation to governments. They alone have the capacity to deal with the magnitude of the problem, to provide the necessary resources, and to implement suitable policies.
Non-governmental organizations and financial institutions should also participate in such an initiative.
CHALLENGES
In the United States the National Academy of
Sciences and the Smithsonian Institution created the National Sciences Resources Center
(NSRC) in 1985.
• The mission of this unique organization is to improve the K –12 learning and teaching of science for all students in the United States and throughout the world.
• After 22 years of continuous an dedicated efforts with facilities and funds many times those available in Latin American and Caribbean countries, (NSRC) claims to have reached 25% of the National school districts .
CHALLENGES
In Colombia, Pequeños Cientificos was created on year 2,000 and is covering about 30,000 children representing only 0,6% of a total of
5,200,000 children in grades
0 to 5 th.
Actually, we only have IBSE projects in 11 countries.
16 Academies are participating in the IANAS-PSE.
The OAS has 35 registered countries. Many of these countries don’t even have and Academy of Science.
CHALLENGES
• The individual projects face continuous and difficult challenges to survive and grow
•Funding
• Few projects have considerable and stable governmental funding. Maybe Chile and Panama are the best examples of national government support.
• Brazil, Mexico, Argentina have government support but in a limited and restricted way.
CHALLENGES
• Colombia receives limited funds from some regional educational authorities and survives thanks to support from private enterprises.
• Clearly we have to convince governments that the best inversion they can make for future development of our countries is in education and we have to demonstrate that IBSE methodology is the best for learning science.
CHALLENGES
Scaling up .
Going from a small or pilot project to a large one brings new difficulties in organization and quality. Specially, problems are encountered in the distributions of materials and the control of quality in the teaching and learning process
Of course, as the project grows more funds are needed for sustainability.
CHALLENGES
Evaluation
IBSE projects require constant evaluation of all the processes involved to control and improve the quality of those processes (formative evaluation) and it is also necessary to evaluate the results obtained after the processes have been operating for a certain amount of time.
(Summative evaluation). We also have to prove, to convince governments, that results using
IBSE methodology are better that those obtained by other methods.

Professional development
Professional development to instruct acting teachers with little or non formation in science and IBSE methodology
In every new educational project an internal program of professional development should be implemented to allow teachers to grow continuously in scientific knowledge and capacity to guide children to learn science.
Modules
Up to 2007, most of the modules that were being used in
Latin America had been originally produced in the United
States or France. There are topics which have to be produced locally to reflect local conditions. This effort has already began mainly in Chile and Brazil.
Some of the children instructed by IBSE projects are going already into middle and high school. There is a great pressure for appropriated modules and laboratory materials that will allow schools to continue using the same methodology in middle and high school.
Some efforts are being made but the problem has not been solved.
All the Academies of the world have the dream of giving every child in our planet an education in science of high quality, the challenge is to make this dream become true.
